What will a quiz be without some questions? Here's how we can deal with the QuestionViewModel.cs file that we need to add within the /ViewModels/ folder:

using Newtonsoft.Json; 
using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Linq; 
using System.Threading.Tasks; 
 
namespace TestMakerFreeWebApp.ViewModels 
{ 
    [JsonObject(MemberSerialization.OptOut)] 
    public class QuestionViewModel 
    { 
        #region Constructor 
        public QuestionViewModel() 
        { 
 
        } 
        #endregion 
 
        #region Properties 
        public int Id { get; set; } 
        public int QuizId { get; set; } 
        public string Text { get; set; } 
        public string Notes { get; set; } 
        [DefaultValue(0)] 
        public int Type { get; set; } 
        [DefaultValue(0)] 
        public int Flags { get; set; } 
        [JsonIgnore] 
        public DateTime CreatedDate { get; set; } 
        public DateTime LastModifiedDate { get; set; } 
        #endregion 
    } 
} 
 

As we can see, this is quite similar to the QuizViewModel, except that it has slightly different properties; one of these is the QuizId, which is rather obvious since each question will be related to its Quiz in a classic one-to-many relationship; each single Quiz will have multiple Questions.
